Q4: [1.5 pts] In an experiment to check conservation of angular momentum, a student obtains the results shown in the table below for the initial and final angular momenta (L and L', respectively) of a rotating system. Using the below data, calculate the value of Delta L = L - L', as well as the error Delta(Delta L). For each set of data, are the student's results consistent with conservation of angular momentum (i.e. does Delta L equal zero within experimental uncertainty)?

Answer 1

a)Deltaa(L)=-29.7�0.9 $\delta (\Delta L)=$ 0.9 Not Conserved since it is not withing error about 0.

b)Deltaa(L)=-0.6�0.6 $\delta (\Delta L)=$ 0.6 Conserved Since it is within error about 0.

c)Deltaa(L)=-2.2�0.2 $\delta (\Delta L)=$ 0.2 Not Conserved.

d)Deltaa(L)=1�4 $\delta (\Delta L)=$ 4 Conserved.

e)Deltaa(L)=1�6 $\delta (\Delta L)=$ 6 Conserved.

f)Deltaa(L)=-4�4 $\delta (\Delta L)=$ 4 Conserved.
